果树黄化病研究进展

黄化病是植物受到有害生物侵染或不良气候、土壤、人为等各种非生物因素胁迫,导致叶片失绿。近年来,果树黄化病发生面积不断扩大,造成树体衰弱甚至死亡、产量下降等不良后果,给果农带来了严重的经济损失,影响果树产业的健康发展。该文通过对果树黄化病发生因子、防治方法等进行综述,以期为黄化病的研究和防治提供一定的理论参考。

Research Advances on Yellow Leaf Disease of Fruit Trees

Tree weak even death, de- cline of production,serious economic losses,the healthy development of the fruit industry were effected by yellow leaf disease. Occurrence factor ,prevention methods of fruit trees yellowing disease were reviewed in order to provide a theoretical reference for the yellow disease research and prevention.
